Abstract
A memory system including a non-volatile memory device and a memory controller is provided. When a read operation on a first data initially output from the non-volatile memory device during a first read operation is successful, the memory controller may change a read voltage for reading a second data stored in the non-volatile memory device during a second read operation.
